Term used by rapper Xzibit to refer to anyone he happens to be speaking to at the time. Often precedes a redundant revelation that he has heard said dawg likes something, so he has put a related object in that dawg's car so they can observe said enjoyable something while they drive.

"Yo dawg, I heard you like driving, so I put a car in yo' car so you can drive while you drive."
-Xzibit
